Description
A new method is proposed for identification of the outermost magnetic surface of tokamak plasmas. The method is based on the analytical solution of the Grad-Shafranov equation in a vacuum region under the toroidal coordinates. This method is applicable to accurate feedback control and real-time visualization of various plasma configurations, and robust to the loss of sensors or the existence of signal noise. (author)
